vcpupin will fail when maxvcpus is larger than current vcpu:

This for loop was introduced by: commit 34f77437da884f9cf0e2450f25f373b17cf527e2 qemu: fix recording of vCPU pids for MTTCG
which started recording TIDs for TCG as well. Skipping it for VIRT_QEMU reverts the benefits for multithreaded TCG, while leaving the loop broken for VIRT_KVM when not all vCPUs are enabled.
The proper fix here would be to stop considering zero TIDs as duplicate.
Ok, I will send a v2 patch. Thanks.
